Bulb onion farming can be a highly profitable venture, but many farmers struggle right from the nursery stage. The excitement of sowing seeds often turns into frustration when the seedlings fail to thrive or die off. Having interacted with many farmers across different regions, I have identified key reasons why bulb onion seedlings are lost at this crucial stage.
1. Poor Seed Selection
The foundation of a good onion nursery starts with quality seeds. Many farmers buy seeds from unreliable sources, leading to poor germination and weak seedlings. Some opt for cheap seeds, not knowing they may be old, poorly stored, or of low genetic quality. Certified seeds from reputable suppliers may be expensive but are worth the investment.
2. Poor Bed Preparation
A well-prepared nursery bed is critical for seedling survival. Many farmers fail to create fine-textured beds, leading to poor seed soil contact. Others do not add well-decomposed manure or use soil that is too compacted, making it hard for seedlings to develop strong roots.
3. Overwatering or Underwatering
Water management is one of the biggest challenges at the nursery level. Some farmers overwater, creating a damp environment that encourages fungal diseases like damping-off. Others underwater, especially in hot regions, causing the tiny seedlings to dry out before they even establish. The key is to keep the soil moist but not waterlogged.
4. Poor Disease and Pest Management
Many farmers ignore early stage disease prevention, thinking their seedlings are too young to be affected. However, diseases such as damping-off, caused by fungi, can wipe out an entire nursery in days. Pests like onion thrips can also destroy young plants. Regular monitoring, proper spacing, and using organic or recommended chemical controls can prevent losses.
5. Failure to Mulch Properly
Mulching plays a crucial role in moisture retention and temperature regulation, but many farmers either skip it or use thick mulch that suffocates seedlings. It is important to mulch for at least the first week up to emergence. Failure to do so can lead to moisture loss, slowing germination. However, if the mulch is left for too long, it can cause seedlings to turn yellow and die due to excess warmth and lack of sunlight.
6. Wrong Irrigation Methods
Sprinkler irrigation is common in onion nurseries, but some farmers use high-pressure sprinklers that wash away seeds or damage delicate seedlings.
Additionally, using a basin irrigation system may be risky if you aren’t keen. The soil near the water entry point can be dragged to one corner, creating an imbalance that buries or uproots seedlings, leading to losses. Proper leveling and controlled water flow are necessary to avoid this.
7. Lack of Proper Hardening
Many farmers fail to harden their seedlings before transplanting. This sudden transition from nursery to open field leads to high transplant shock and mortality. Reducing watering frequency and exposing seedlings to gradual sunlight before transplanting helps them adjust better.
Losing bulb onion seedlings at the nursery level can be frustrating, but understanding these mistakes can help prevent losses. The key is to start with quality seeds, prepare a well-drained and fertile nursery, manage water correctly, prevent diseases early, and handle seedlings with care.
If you're struggling with your nursery, don't hesitate to seek advice. Farming is a journey, and learning from mistakes is part of the process!
